It's really hard to give a time for this, like Ian said it's when the resin isn't sticky anymore and still rubbery, use a short piece of strip material to check and check where the resin's run down the glass off the hull to not disturb the resin on the hull. Testing with your finger isn't a great idea, don't want direct contact with uncured resin on your skin.
